IPC: H04B10/278
Filed: 1989-12-18
Abstract: PURPOSE:To uniformly control each equipment by converting an analog signal into a digital signal for control, transmitting the converted signal to each equipment and generating a pulse with the same means at each equipment. CONSTITUTION:A pulse width control DC voltage generating section 1 generates an analog signal (DC voltage) 6 proportional to a pulse width required finally, converts the signal into a serial digital signal 8 through an A/D conversion section 2 and a parallel/serial conversion section 3 and the resulting signal is sent to a data bus 9 from a serial signal transmission section 5. A reception section 11 at a reception side regenerates a serial digital signal 16, a serial/ parallel conversion section 12 regenerates a parallel digital signal 17 and inputs the result to a pulse generating section 13 to generate a pulse 18 proportional to the original control DC voltage. Thus, the pulse signal having a pulse width proportional to a transmission side DC voltage is obtained. Then lots of instruments are uniformly remote-controlled.

Abstract: PURPOSE: To improve noise resistance and the like by setting the carrier frequency in adjacent closed blocks and the correlation coefficient of a correlative matched filter in a specified condition in a device for supplying carrier wave from the starting side of a rail to the terminal side and demodulating a received diffusion signal to control the action of a track relay. CONSTITUTION: Carrier wave of specified frequency is diffused by a multiplier 2 by a PN code from a PN signal generator, and this diffusion signal is sent out to the starting end side of a rail by transmitter 4 and received by a receiver 5 installed at the terminal side of the rail. After demodulating the input signal by a multiplier 6, a signal including the PN code is extracted by an LPF circuit 8. A correlative value detecting part 20 detects the correlative value by multiplying an extraction signal by a specified correlation coefficient, and the presence of a train in a closed block is detected on the basis of the detection value. In this case, the carrier wave frequency (f) of each closed block in a group of plural closed blocks is set to the condition of f=f0 + (diffusion bandwidth) ÷(PN code chip number × 2) × N.

Title: Magnetic recording device
Inventor: TAKADA YOSHINAO
IPC: G11B5/09
Filed: 1989-12-21
Abstract: PURPOSE:To enable high-density recording without increasing the performance of a head, etc., by using a filter which passes the secondary higher harmonic of a '10010' pattern in an MFM series and cuts off a tertiary higher harmonic of '1001000'. CONSTITUTION:A delay equalizing filter 31 is the filter having such transmission characteristics without delay distortion that the secondary higher harmonic of the 1-2 pattern is passed and the tertiary higher harmonic of the 2-3 pattern is nearly cut off. The filter 31 consists of two stages of secondary grating type all-pass filters and its constant is so determined that the delay time variation of the rear stage of the low pass filter is compensated. The output of this filter 31 is passed through a specific circuit and an AND gate 38 ANDs the outputs of a zero-cross comparator 37 and a comparator 36 for shoulder cutting and outputs a real peak detection pulse from which a false peak is removed. Consequently, high frequency noises of >=5 MHz are attenuated and a signal with a high SN ratio is obtained.

Title: Marine rudder
Inventor: FUKUDA MASAATSU
IPC: B63H5/16
Filed: 1990-11-30
Abstract: PURPOSE:To collect the rotation flow of propeller alternating current as thrust, and improve propulsive efficiency by providing a forward projection at the fin mounting position of a rudder leading edge in such a way as to come near a propeller boss cap. CONSTITUTION:A rudder 5 is fitted with fins 6A and 6B transversely extended at the center height of a propeller 2, and the fins 6A and 6B have opposite camber vertically, so as to generate equal lift upon receipt of the rotating propeller alternating current. A bulbous forward projection 7 is provided on the leading edge of the rudder 5 in such a way as to come near a propeller boss cap 3 at propeller center height. Even when a gap is rather excessive between the propeller boss cap 3 and the leading edge of the rudder 5, the rotating alternating current of the propeller 2 is radially expanded with the projection 7, and reaches the fins 6a and 6B effectively. Consequently, the forward propulsive component of generated lift becomes a part of thrust, thereby improving propulsive efficiency.

Title: Cultivation method of plant
Inventor: UCHIDA HIRONORI
IPC: A01G9/00
Filed: 1996-12-10
Abstract: PROBLEM TO BE SOLVED: To provide a safe and inexpensive cultivation method for plants capable of preventing the infiltration and propagation of saprophytic bacteria and pathogenic bacteria. SOLUTION: The seeds of radish sprouts are subjected to a lactic acid bacterium treatment in the clean state of the surfaces of the seeds by washing and swelling the seeds (S1, S2), by which the lactic acid bacteria are fixed to the surfaces of the seeds (S3). As a result, the surfaces of the radish sprouts maintain the state of covering the surfaces with the lactic acid bacteria at all times in the growth process of the radish sprouts which root and germinate afterward, by which the infiltration and propagation of the saprophytic bacteria and the pathogenic bacteria are suppressed. The surfaces of the radish sprouts are more surely coated with the lactic acid bacteria by spraying the lactic acid bacteria at need (S6, S8) after seeding (S5)) or at the time of growth in greenhouses.

Title: High mounted stop lamp for automobile
Inventor: KAKIHIRA SUSUMU

Filed: 1987-12-28
Abstract: PURPOSE:To remove harmful light to a driver by making a ray which is reflected by a rear window and directed to the front of an automobile not to be incident on a rear-view mirror or making reflected light by the rear-view mirror not to be incident on the sight of the driver. CONSTITUTION:Considering the light track of a light L which is directed upward from a front lens 20 and whose incident angle is the largest with respect to a rear window 1, the foremost projecting point P2 of a shade upper part zone 17a is formed in such a way that the reflected light L1 by the rear window 1 of the light L is directed to the lower part of the bottom end point P3 of a rear-view mirror 60. In this case, since the angle of reflection of light which is reflected by the rear window 1 is smaller than the angle of reflection theta of the light L, when the light L is directed to the lower part of the bottom end point P3 of the rear-view mirror 60, all light which is reflected by the rear window 1 and directed to the front of an automobile is directed to the lower part of the rear-view mirror 60. If no reflected light by the rear window 1 is incident on the rear-view mirror 60 at all, a driver will not be dazzled. Also, even if the reflected light by the window 1 is reflected by the mirror 60, there is no problem if the light is off the view of the driver.
